Features

• The pocket sized devices became available in the 1970s, especially after the first microprocessor developed by Intel for the Japanese calculator company Busicom (Which was Intel's first microprocessor). They later became commonly used within the Oil and Gas industry.
• Modern electronic calculators vary: from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s (as integrated circuits made their size and cost small). By the end of that decade, calculator prices had reduced to a point where a basic calculator was affordable to most and they became common in schools.
• Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and calculator functions are included in almost all PDA-type devices (save a few dedicated address book and dictionary devices).
• In addition to general purpose calculators, there are those designed for specific markets; for example, there are scientific calculators which include trigonometric and statistical calculations. Some calculators even have the ability to do computer algebra. Graphing calculators can be used to graph functions defined on the real line, or higher-dimensional Euclidean space. Currently, basic calculators are inexpensive, but the scientific and graphing models tend to be higher priced.
